Maybe not. Sierra Leone seems to be officially Imperial according to this article, but at least they are working on it. If only we had the courage to repeal and replace, instead of officially maintaining the mess known as "dual."
http://news.sl/drwebsite/publish/article_200515520.shtml After the first and second reading of the bill entitled Weight and Measures Act 2009 by the Minister of Trade and Industry Hon. David Carew, the House of Parliament on Tuesday 1st June 2010 unanimously consented to send the bill to the Legislative Committee for more deliberations and scrutiny. Earlier the minister had convinced the Honorable House that the Bill is intended to repeal and replace the Imperial System of Measurement as well as validate the use of the Metric System for measurement based on the International System of Units to provide for the comparison and verification or weight and measures, and to also provide for other related matters. He said the Ordinance Act that was passed into law in the 1961 has become obsolete for the growing economy, adding that Sierra Leone being one of the few countries still stuck to the old law, the need was there to pass this new law. . . .
